Special terms and conditions for prepaid cards
The free minutes, SMSes and MBs are valid in Belgium and Europe, with the exception of premium numbers, and remain valid for 30 days after you top up. These minutes and SMSes will not be transferred to another tariff plan. With each new top up of at least €10 within 30 days, your unused free minutes and SMSes expire and are replaced with new free minutes and SMSes. If you top up again within 30 days for at least €10, the period of validity for any remaining MBs is extended by 30 days. If you top up for €5 before the 30 days have elapsed, the free minutes, SMSes and MBs from your last top up remain valid until the expiration date. If you exceed the free volume of MBs, the data traffic beyond that volume is deducted from your credit in KB increments at a price of €0.50/MB.
